SCHMIDT PneumaticPress

Transcription

1 Maximum Pressing orce from 1.6 to 60 kn The SCHMIDT PneumaticPress range consists of a modular system suitable for transforming, joining and assembling operations optimally within the pressing capacities of kn. With the addition of the SCHMIDT PressControl 70 or 600 and the optional process monitoring, these presses become EC type-approved, CE-conformed workstations. Therefore these press systems can be used in either single cycle mode or automatic mode. The application determines the selection of the press system. Consideration is given to the flexible design of the assembly location taking into account the ergonomic and safety aspects. These characteristics are achieved by means of a finely adjusted, modular type product range. The efficiency and increased process reliability of these press systems have been proven many thousands of times, in single applications, semi-automated assembly systems and have been integrated into automated production lines.

2 Example of a System Design with a Direct Acting Press 1 Cylinder Unit Maintenance-free specially developed for the assembly technology; with flow control for speed regulation of the downstroke. 2 Press Head Unit The working height can be rapidly & accurately adjusted due to the height adjustment s ease of use. Can be used without the frame as processing station in automated installations. 1 3 Pneumatic Control Package Two-channel pneumatic package (as shown) is based on a modular valve block, designed to operate with filtered, nonlubricated air, supply pressure range of 3 6 bar. 4 orce Control The press force output can easily be controlled via a separate pressure regulator and pressure gauge (not shown). 5 Ram With precision bore for tool holding and built-in adjustable stop. 3 6 rame With precision machined press head guide rails. 7 ixture Mounting Plate With precision T-slot and bore for tool location SCHMIDT Presses

3 Principle of Operation unctional Description considering the Example of a 3-chamber Pneumatic Cylinder In working stroke, three pistons 7 connected by the piston rod 6 are pressurized with compressed air via the air connection 1 and move downward. The air below the pistons exhausts from the cylinder chambers via the depressurized connection 2 and the breather vents 3 and 4. The ram 5 extends up to the maximum working stroke. In return stroke, the upper cylinder chambers are depressurized via the connection 1 and only the bottom piston is pressurized with compressed air via the air connection 2. Ambient air enters in both remaining cylinder chambers via the breather vents 3 and 4. The ram with the three pistons moves upward. This construction has the same effect as a parallel connection of three cylinders. Thus, a powerful working stroke is achieved with a compact design as well as an economic use due to the low air consumption in the return stroke. The stroke can be limited by setting the Stroke Limit Block 8 to an approximate, desired position. The gap between Stroke Limit Block and Stroke ine Adjustment 9 now determines the maximum stroke that the ram can travel. In order to fine-tune this stroke, the ine Adjustment Nut 9 can be adjusted. All direct acting presses have a built-in permanent magnet 10. This magnet facilitates sensing of the ram position via tie rod mounted sensors eatures Optimally adapted to individual requirements due to its modular design Process optimization by means of adjustable parameters (stroke, force, speed) Easy adaptation to different tool and part heights because of simplistic stroke and height adjustment Additional safety measures when using heavy tools due to the optional device for retention of ram in home position Optional end position request via cylinder switch as signal transmitter for peripheral processes Low noise level (< 75 dba) Double-acting, wear-resistant cylinders with low air consumption for the return stroke High flexibility due to short changeover time Long service life and high precision due to wear-resistant Teflon coated bushings at top & bottom of cylinder Precision ground ram Precision double ram guides 2 5 Simply the best! 23
